Usage Guidelines
When you change the SDM template by using the sdm prefer global configuration command, you must
reload the switch for the configuration to take effect. If you enter the show sdm prefer command before
you enter the reload privileged EXEC command, the show sdm prefer command shows the template
currently in use and the template that will become active after a reload.
The numbers displayed for each template represent an approximate maximum number for each feature
resource. The actual number might vary, depending on the actual number of other features configured.
Expressions are case sensitive. For example, if you enter | exclude output, the lines that contain output
do not appear, but the lines that contain Output appear.
